Sinopec R&O Air Compressor / Circulating Oil 68 is a rust and oxidation (R&O)-inhibited, antiwear circulating oil developed for use in circulation systems, centrifugal air compressors, geared turbines, lightly loaded enclosed gear drives and many other industrial applications. It contains a low level of ashless (zinc-free) antiwear additive for mild wear protection.

Sinopec R&O Air Compressor / Circulating Oil 68 is suitable for use in:

  • All types of reciprocating air compressors where a DIN 51506 VDL oil is required, for once-through cylinder lubrication and also to lubricate compressor crankcases.
  • Single-stage and multi-stage reciprocating air compressors.
  • Compressors that handle air, inert gases (such as nitrogen, argon, neon and helium), carbon dioxide, carbon monoxide and blast furnace gas.
  • Stationary and mobile units.
  • Some rotary vane and screw compressors.
  • Caution: not recommended for breathing air compressors.


Features and benefits

  • Excellent lubricating properties protect moving compressor parts against wear and extend component life.
  • The highly refined mineral base oil has outstanding thermal and oxidation stability and low carbon-forming tendency compared with conventional mineral oils, and this leads to good compressor cleanliness, reduced deposits and improved compressor efficiency, even when air discharge temperatures are high (up to 220°C).
  • Reduced deposits in discharge lines, reducing the risk of fires and explosions.
  • Good anti-rust and anticorrosion properties protect cylinders and discharge valves from rusting and corroding, enhancing equipment life and performance, and prolonging service intervals.
  • Excellent water-separation characteristics ensure that condensed water vapour can easily be separated from the lubricant and prevent the formation of emulsions (which could block the oil/air separator (coalescer) in some compressors), therefore prolonging coalescer life, and reducing equipment downtime and maintenance costs.
  • Improved oil quality leads to longer maintenance and overhaul intervals and extended oil drain intervals, compared with poorer quality products.
